The other osseous tissue type is cortical bone also called compact bone.ArcoMechanochemistry: Mechanochemistry or mechanical chemistry is the coupling of mechanical and chemical phenomena on a molecular scale and includes mechanical breakage, chemical behaviour of mechanically stressed solids (e.g.Internal fixationHip fractureWorld Osteoporosis Day: World Osteoporosis Day is observed annually on 20 October, and launches a year-long campaign dedicated to raising global awareness of the prevention, diagnosis and treatment of osteoporosis and metabolic bone disease. Organized by the International Osteoporosis Foundation (IOF), World Osteoporosis Day involves campaigns by national osteoporosis patient societies from around the world with activities in over 90 countries.Knee pain: Knee pain is a common complaint for many people. There are several factors that can cause knee pain.Epiphysis: The epiphysis (OED 2nd edition, 1989 as .Entry "epiphysis" in Merriam-Webster Online Dictionary.Hip resurfacing: 155px|right|thumb|The BHRMinimally invasive hip resurfacing: Minimally invasive hip resurfacing (MIS) is "total or partial hip surgery that can be carried out through an incision of less than 10 cm (3.94 inches) without imparting great forces on the anatomy or compromising component positioning"Comis Orthopaedics websiteOsteotomyCallus (cell biology): Plant callus (plural calluses or calli) is a mass of unorganized parenchyma cells derived from plant tissue (explants) for use in biological research and biotechnology. In plant biology, callus cells are those cells that cover a plant wound.Demineralized freeze dried bone allograft: Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its [novo] bone formation properties.Bowers, GM, et al.Cement: A cement is a binder, a substance that sets and hardens and can bind other materials together. The word "cement" can be traced back to the Roman term opus caementicium, used to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder.X-ray microtomography: X-ray microtomography, like tomography and x-ray computed tomography, uses x-rays to create cross-sections of a physical object that can be used to recreate a virtual model (3D model) without destroying the original object. The prefix micro- (symbol: µ) is used to indicate that the pixel sizes of the cross-sections are in the micrometre range.Traction substation: A traction substation or traction current converter plant is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or trolleybuses with traction current.Nonunion: Nonunion is permanent failure of healing following a broken bone.Bone tumorRobert BrobergDynamic strain aging: Although sometimes dynamic strain aging is used interchangeably with the Portevin–Le Chatelier effect (or serrated yielding), dynamic strain aging refers specifically to the microscopic mechanism that induces the Portevin–Le Chatelier effect. This strengthening mechanism is related to solid-solution strengthening and has been observed in a variety of fcc and bcc substitutional and interstitial alloys, metalloids like silicon, and ordered intermetallics within specific ranges of temperature and strain rate.LUSAS: LUSAS is a UK-based developer and supplier of Finite Element Analysis (FEA) application software products that bear the same name.Metallosis: Metallosis is the putative medical condition involving deposition and build-up of metal debris in the soft tissues of the body.OssificationOsseointegration: Osseointegration derives from the Greek osteon, bone, and the Latin integrare, to make whole. The term refers to the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant.Herbert screw: The Herbert screw (invented by Timothy Herbert) is a variable pitch cannulated screw typically made from titanium for its stainless properties as the screw is normally intended to remain in the patient indefinitely. It became generally available in 1978.Revision using distal inflow: Revision Using Distal Inflow (RUDI) is a surgical treatment for Dialysis-associated Steal Syndrome.Alendronic acidChalkstick fracture: Chalkstick fractures are fractures, typically of long bones, in which the fracture is transverse to the long axis of the bone, like a broken stick of chalk. A healthy long bone typically breaks like a hard woody stick as the collagen in the matrix adds remarkable flexibility to the mineral and the energy can run up and down the growth rings of bone.DeoxypyridinolineHypochondrogenesisCalvaria (skull): The calvaria or skullcap (feminine Latin noun with plural calvariae; however, many medical texts list the word as calvarium, neuter Latin noun with plural calvaria) is the upper part of the neurocranium and covers the cranial cavity containing the brain.Ilizarov apparatusDuctility: In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire. Malleability, a similar property, is a material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling.Gestational age: Gestational age (or menstrual age) is a measure of the age of a pregnancy where the origin is the woman's last normal menstrual period (LMP), or the corresponding age as estimated by other methods. Such methods include adding 14 days to a known duration since fertilization (as is possible in in vitro fertilization), or by obstetric ultrasonography.Dense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.A-scan ultrasound biometry: A-scan ultrasound biometry, commonly referred to as an A-scan, is routine type of diagnostic test used in ophthalmology. The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders.Bone pathology: Bone pathology, also known as orthopedic pathology is a subspecialty of surgical pathology which deals with the diagnosis and feature of many bone diseases. It uses gross and microscopic findings along with the findings of in vivo radiological studies, and occasionally, specimen radiographs to diagnose diseases of the bones.
